The validity period of an F-1 visa depends on your country of citizenship. For example, for citizens of Western Europe, Australia, Japan, etc., F-1 visas generally are valid for 60 months. In your case, however, where you’ll be attending a 6-month ESL program, the visa may only be valid for the duration of the program.
In any event, if you decide to continue your studies after completing your ESL program, you can extend your status in the US without having to travel abroad.
